Force snapcraft to not clean part

snapcraft

Is it possible to force snapcraft to not clean a part? I have a (cmake) build which failed at 90% due to missing build-packages. I’d like to fix build-packages, but whenever I do that, the entire build gets lost.

Is there anything I can do to avoid rebuilding the first 90%?

There is no way to currently request this.

core20-based projects are far less aggressive about cleaning parts for incremental development, but it is still cleaning after build-packages is changed unfortunately.
